Let's divide 72415565 by 205
The aim is to understand the frequency of 205 in 72415565.

Advancing to step 1:
205 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 205

Moving on to step 2:
When dividing 72 by 205, we get 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 205

Advancing to step 3:
The number 205 fits into 724 3 times, leaving a remainder of 109.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 615 from 724 and we're left with 109.
Bring next digit (1) of the dividend behind the 109 and repeat the process: 1091 / 205

Going ahead to step 4:
When dividing 1091 by 205, we get 5 with a remainder of 66.
Write down 5 as next digit of the result. 
Result so far: 35.0
The remainder is 66 after subtracting 1025 from 1091.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 205

Advancing to step 5:
665 divided by 205 is 3 with a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 353.0
If we take 615 away from 665, we end up with 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 205

Moving on to step 6:
If we divide 505 by 205, we get 2 and a remainder of 95.
Record the quotient 2 as the next digit in the result. 
Result so far: 3532.0
If we take 410 away from 505, we end up with 95.
Take the next digit (6) from the dividend and append it to 95, then repeat: 956 / 205

Advancing to step 7:
When dividing 956 by 205, we get 4 with a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 35324.0
If we subtract 820 from 956, we get 136.
Take the next digit (5) from the dividend and append it to 136, then repeat: 1365 / 205

Let's proceed to step 8:
The number 205 fits into 1365 6 times, leaving a remainder of 135.
Use 6 as the next digit of our solution. 
Result so far: 353246.0
Deduct 1230 from 1365 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 9:
If we divide 1350 by 205, we get 6 and a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 353246.6
If we take 1230 away from 1350, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
The number 205 fits into 1200 5 times, leaving a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 353246.65
If we subtract 1025 from 1200, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 11:
If we divide 1750 by 205, we get 8 and a remainder of 110.
The next digit of our result is 8. 
Result so far: 353246.658
The remainder is 110 after subtracting 1640 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 12:
205 goes into 1100 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 353246.6585
Subtract 1025 from 1100 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 13:
205 can be fit into 750 3 times, resulting in a remainder of 135.
Use 3 as the next digit of our solution. 
Result so far: 353246.65853
Subtract 615 from 750 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 14:
205 can be fit into 1350 6 times, resulting in a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 353246.658536
The remainder is 120 after subtracting 1230 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 15:
205 goes into 1200 5 times with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 353246.6585365
If we subtract 1025 from 1200, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 16:
1750 divided by 205 is 8 with a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 353246.65853658
Subtracting 1640 from 1750 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final outcome is 353246.65853658, with a leftover of 1.1e-07.
